Code character autocorrect in NetBeans?

Question

Java

In general, I had an aesthetic need to replace the function display code Math.sqrt(arg)in the form of a radical sign √(arg)
. Can you please tell me how this can be implemented?
And ideally √(arg), push the function into a separate lib, so that the result is something like this:

import com.author.radical;          //та самая либа

public class Home{
   //куча кода
   float var1 = (float) √(100);     // var1 = 10.0f
   //куча кода
}
